Definitions
- the present invention relates to a method for maki decorative webs, sheets or panels.
- Such decorative plastic webs etc can be made in that differently coloured granules, paste droplets, powders etc are fused together so as to form irregularly marbled layers of mingled shades, which may have a subs ⁇ tantial thickness. Such a web is resistant to wear but is highly restricted as to the choice of pattern, becaus only products of mingled shades can be obtained.
- Another technique of making decorative plastic webs etc involves applying a pattern in the form of a thin printed film of high pigment concentration to a plastic carrier layer and covering it with a transparent surface layer. In contrast to the first-mentioned technique, the latter technique allows the web to be provided with any desired pattern, but one drawback is that the pattern must be protected by a wearing layer which is decisive of the wearing strength of the product. If the wearing layer is worn out, the pattern layer will soon be ruined, and the web must be discarded for aesthetic reasons.
- an arrangement has been provid by means of which plastic material of different colour and/or structure is sprayed through nozzles onto a carrier web during relative movement of the carrier web and the nozzles.
- This relative movement is controlle by an electronic system, and comparatively complicated patterns can be formed.
- the product obtained is coloured throughout and thus resistant to wear, but sometimes the spraying of the plastic material causes problems.
- the object of the present invention is to provide an alternative, simpler method for making decorative plastic webs etc having a pattern which is the same throughout the product or at least is of considerable thickness and, if desired, can be extremely complicated.
- a liquid is applied to a support in a prederermined pattern
- 5 b) a decorative material in the form of powder, granules or flakes is applied to said support, c) any decorative material which, when applied, lies outside the liquid pattern, and any excess of decora ⁇ tive material, which may occur in said pattern, are - removed
- steps a), b) and c) are repeated the number of times required for the final pattern, while applying every time said liquid in a new pattern and a decorative material of a colour and/or a structure deviating
- Fig. 1 shows a production line and the associated devices
- Figs 2-4 show a valve assembly and the associated nozzles in a plan view, end view and perspective view.
- the line comprises an endless conveyor belt 24 preferably made of Teflon, which is supported by 30 conventional means, of which only a few rollers are shown in the Figure.
- the symb are designated 1-23, and the meaning of their will now be explained in detail.
- Numerals 1-3 designate devices by means of which a support can be applied to the conveyor belt 24.
- the support can have the form of a release paper, or a plas ⁇ tic layer which is insulated or reinforced, or it can be designed in some other manner, but it should be empha ⁇ sised that such a support is not necessary - during the following steps, it is possible to work directly on the belt 24, provided that it is made of a suitable material.
- a device for applying liquid, e.g. water, is designated 4 and comprises, as shown in Figs 2, 3 and 4, a number of valve assemblies 25 each of which is provided with a number of nozzles 26.
- valve assem ⁇ blies 25 are mounted on a distribution pipe 28 in such manner that they extend somewhat obliquely in relation to the direction of motion of the underlying belt.
- 16 valve assemblies 25 are arranged, each having 8 nozzles 26.
- the nozzles 26 are connected to the distribution pipe 28 which is, in turn, connected to a supply of liquid (not shown), and each nozzle can be opened and closed by means of a valve (not shown).
- the nozzle valves are opened and closed by electronic control means mounted in a casing 27 arranged above the valve assemblies.
- each nozzle 26 can emit a very thin jet of liquid onto the underlying belt 24 or the support applied thereto, and because of the large number of nozzles, also most complicated liquid patterns in the form of points (islets), and interrupted or coherent lines in any desired direction, as well as larger fields of liquid can be applied.
- the belt reaches a dosing device 5, which is adapted to apply a decorative material, usually a colorant powder, to the liquid pattern just applied.
- a dosing device 5 which is adapted to apply a decorative material, usually a colorant powder, to the liquid pattern just applied.
- the dosing device 5 may comprise a trough having a discharge slit and a knurled roller arranged in the trough, and normally supplies the powder over the entire width of the belt, which however does not matter as will appear from the following.
- an IR element 6 is mounted which can warm the powder and the liquid such that the colorant powder applied to the liquid pattern sinks.
- a suction device 7 which sucks off all the colorant powder supplied by the device 5 and not adhering to the liquid pattern. Instead of removing the powder by suction, it can be removed by shaking or brushing. This means that both material outside the pattern and excess materia in the pattern are removed and returned to the dosing device 5.
- the layer of powder on the belt 24 now has a clearly defined coloured pattern.
- Fig. 1 shows two such further stations in which said devices are designated 8, 9, 10 and 11 and, respectively, 12, 13, 14 and 15.
- the liquid application devices 8 and 12 By means of the liquid application devices 8 and 12, other patterns are applied than that produced by the device 4 as described above, and powders of diffe- rent colour and/or structure are applied by means of the devices 9 and 13.
- the pattern normally covers the entire width of the belt after the last station.
- the belt 24 After the belt 24 has passed all stations for appli cation of liquid and colorant powder, it will reach a levelling device 16, preferably a roller of conventional design which touches the powder layer. Subsequently, the belt runs into a curing or gelating furnace 17 of conventional design. Then follows a smoothing and coolin device 18, which is also desi ⁇ ned in conventional manner. In some cases, one wishes to apply a further layer to the web now cured. If so, this occurs at 19 where a thin layer of a suitable material is spread over the entire web, which is precured in a subsequent device 20 and is finally cured in a device 21. The finished web is smoothed and cooled at 22, and it is wound at 23.
- a levelling device 16 preferably a roller of conventional design which touches the powder layer.
- the belt runs into a curing or gelating furnace 17 of conventional design. Then follows a smoothing and coolin device 18, which is also desi ⁇ ned in conventional manner. In some cases, one wishes to apply a
- liquid is here meant all liquids which after the application of powder can, by heating, either be evaporated or be caused to be sorbed by the powder mate ⁇ rial.
- water is pre ⁇ ferred, but many other liquids which are vaporisable or compatible with the powder, are conceivable.
- the liquid can also have the form of a curing agent in a two-component system or be such that it dissolves the applied powder layer.
- the liquid e.g. the water, keeps the plastic granules together, and it will be appreciated that the heating by means of the IR elements before the final treatment is not allowed to go so far that the adhesion between the granules themselves and between the granules and the support is considerably impaired or ceases.
- a layer of a binding agent for example PVC plastic
- the layer of binding agent preferably is applied to a support in a form of a removable release paper, an insulating or reinforcing material or some other suitable material which remains in the finished product.
- PVC powder is dosed over the belt and the layer of binding agent, respectively, and at 3, the excess of powder is removed such that a layer remains over the entire belt, which is of uniform thickness and adheres to the layer of binding agent.
- the method described above is carried out, except that the water is replaced by a binding agent, such as PVC plastic.
- the material which is applied in the liquid pattern by means of the dosing devices 5, 9 and 13, normally consists of colorant powder, but can also be powders, granules or flakes of quite different materials, such as metal, cellulose, mineral etc.
- the surface of the produced web can be smooth and have a surface layer or can have a structure, for example in that no surface layer is applied at 19, or in that the applied surface layer contains bodies of some kind, such that a web is obtained which is suited for use on non-skid floors.
- a relief of the web can be obtained by varying the amoun of supplied liquid and by choosing the after-treatment.
- a foam can also be applied to the web, if desired.
- the web can easily be reinforced by supplying a reinforcing material, as indicated above, or it can have an insulating layer.
- the pattern binding agent is applied, as indicated above directly to the running belt, without the belt being provided with a release paper or a felt, or a layer of binding agent and powder.
- the method according to the invention renders it possible to make webs, sheets and panels of plastic or some other material in practically any desired pattern. Even short series are possible, since the pattern can easily be changed.
